To all whozrz it may concern:

Be it known that we, "WILLIAM 0. KEY- wonrn and THOMAS A. Roninson, citizens of the United States, residing in Peterson,

5 county of Passaic, and State of New Jersey, have invented Improvements in lVarping and Beaming Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and

to letters of reference inarl'ed thereon, which form a part of this speciii "on. I

I This invention relates to Warping-machines;

and it involves certain improvements in this class of machines which result in'the production of a warping-machine whereby the warping operation is considerably simplified and which, furthermore, render the mechanisms or groups of element-s to which they are directed highly ei'licient for the performance of their several functions.

One of the mechanisms or sets of elements above referred tois that means whereby the tendency of the beam or" the warping-n iachine to draw with increasing tension on the threads as the maierial is wound with constantly-increasing thickness upon it is compensated 3o for,and anotheroi said mechanismsis that for effecting the proper tension upon the threads.

The invention consists in a-warping-ma-' chine improved especially along the lines in-- dicated above and hereinafter particularly pointed out and in the combination and arrangement of its various parts The invcntionis "nil coinpanying d ra Figure l. is a g ted mach g it'isatcpplanview ot'said machine. 3 g. dis topplanjv iew oi the main drive-shft and accessory arts, showings portion of toe mechanism whereby power is transmitted. from this shaft to the 4 bcani. Fi 4 is a'view in side elevaticnoof a v a portion of the ina'chinefillnstr'ating a'certain mechanism whereby said v power-transmitting:

The frame a of the machine is substantially 6o rectangular and comprises as parts of its structure two surmonnting and spaced bed-. plates a a the one of which, ct, is considerably larger than the other and is provided at one corner with a projection a ct" desigiiiates support that projects from may also be considered as a portion of the frame of the machine and is steadied by braces of. Y

b is the main drive-shaft. It is journals-d 7o transversely of the frame and beneath the bed-plate o, in the upper side rails 11'1") of said frame and is movable to a slight extent longitudinally in its bearings. At one of its ends carries a friction-disk bflwhich i. keyed 7 5 or otherwise secured in place, so as to revolve with the shaft, and which has the central portion of its outer or acting face, dished out or recessed, as at h. At theother of its ends it carries a pulley 0, adapted to receive a drivebelt. (Not shown.)

' c is a substantially arch-shaped bracket that projects outwardly from the side rail b of the frame and carries a fset screw 0 pro-"' vided with a lock-nut o -and having its inner end tapered, as at c ,-'and; projecting into a correspondingly-shaped"recess o in the bottom of a cop cflwhicli receives theend of the andv also a spring 0", that'is'seated in atnoiilarr'ecess orsocket '0 in said shaft. When the setscrew is properly adjusted, it will'be seen that it is the tendency ofthe spring 0 to force theshaft in thedirection of the arrow in Fig. 3. Its action, however,"is limited by a collard, that is disposed between the pnl-. Icy-and the rail b and may be either integral Connecting the side 'rails'b o f the frame I with or separate'from saidi'pulley.

is a pair of parallel rods d, upon which are mounted, soastobe adjusted -to. and from we ea other, a pair of brackets dfl w-hicl'i are ads. ted to provide bearings for the ti'nnnions,

of the beam-carrying mandrel (1 One end of this beam-carrying mandrel is provided with a disk d against which one end of the beam which the mandrel receives is adapted to impinge, said beam being held in place on the mandrel by means of a pivoted clip (Z upon the'other end of the mandrel and adapted to be swung about its pivot to engage the corresponding end of the beam. One of the brackets (Z' is integrally formed with a gearcasiugdflin which is journaled a train of intermeshiug gears 11 one of said gears being mounted on a shaft 0, which is journaled in the side rails I) b and at the end thereof adjacent the friction-disk b carries a bevelgear 0.

e is a shaft which is journaled parallel to the side rail a in brackets e projecting there- .fromand which carries a bevel-gear e, in mesh with the bevel gear 6. This shaft has a feather a, and it carries a friction-wheel e, provided with a keyway which receives the feather r, so that, while the friction-wheel may rotate with the shaft a, it may also be moved longitudinally thereon. The brackets a also constitute supports for a longitudinal] ymovable rack-bar f, that is disposed beneath the shaft e and carries a fork f, provided in its bifurcations with oppositely-disposed pins f that work in a circumferential groove f of a collarf, that forms a part of the friction-wheel e.

r/ is a gear-casing that extends horizontally and outwardly from the frame near the pro-' jection u of the bed-plate a and in which is jourualed a train of geariugg, one of the pinions which comprise this train of gearing, having its teeth in mesh with the teeth g of the rack-barf, a portion of the gear-casing being removed, as shown at g in Fig.4, for this purpose. Secured upon the projection n," by means of screws 9 or in any other desired manneris a disk g, which has its periphery provided with notches 1 disposed at suitable intervals. Penetrating the center of this disk and also the projection a, the gearcasing g, and one of the gears of the train of gearingg" is avertical revoluble shaft h. Said shaft is secured to the gear, which it penctrates, so as to rotate the same, and it carries at its upperend a crank It, havinga two-part handle it", onepart of said handle constituting a lever 71. which is fulcrumed in the other partaud which is actuated bya spring 71. disposed between the parts of said handle, so as to normally force its lower end against the periphery of the disk.

It will be seen that by rotating the crank h, the leverboiug kept from engagement with the notches of the disk g, the rack-barfwill be moved longitudinally, and consequently the position of the friction-wheel relatively to the center of the friction-disk will be altered. llence as the material winds on the beam during the warping operation all that it is necessary for the operator to do .in order to prevent an undue increase of the pull'upon the warp-threads by the beam and to keep the tension uniform throughout the operation is to manipulate the crank h, thus altering the position of the friction-wheel with reference to the center of the friction-disk, as above described, and so altering the speed at which said friction-disk,a11d consequently the beam, will be revolved.

It should beremarked at this point that so long as the friction-wheel is in approximatelydirect alinement with the shaft b-that is to say,.is opposite the dished-out or recessed portion of the disk-it will not be in contact with said disk, because the collar prevents the spring 0 from effecting this. The spring 0 is provided so that the shaft will offer some resiliency to the friction-wheel, and thus the contact between the friction-wheel and the friction-disk will be preserved uniform. By virtue of the dished outor recessed portion 6 of the disk the operator can, furthermore, immediately stop the motion of the beam by hreakingthe connection at this point between the drive-shaft and the mechanism whereby power is transmitted therefrom to the beam.

Upon the bed-plate a, and neareach side thereof are mounted two standards i, each having a pair of integral and'arc-shaped arms 1" and each having a recess i in its most elc vated portion, which aifords a seat for one of the trunnions of a roller or beam 1'". In these standards are f ulcru med upon bolts '6, disposed each side of the recess i two pairs of levers 2' the members of each pair of said le-.

vers being connected by a rod 2', upon which is journaled a roller 6 and also by abracingrod i disposed in projections i of said levers. Extending downwardly from each lever is an integral arc-shaped guidej, which is provided with a longitudinal slotj', at each end of which there is formed in the guide a notch 7. The slots of each pairof guides receive a rod k, that penetrates the arms 1" and is guided for longitudinal movement in the latter by a pin 7;, and that is provided with one or more keys 7& near its ends, which are adapted to engage the notches j of the guides j. One end of each rod is provided with a knob or handle it, between which and thearm is a spring 79*, coiled about the rod and tending to force the knob, and consequently the rod, outwardly.

m and m are two reeds that are mounted on the frame, the one being sustained upon too the extremity of the support a and the other being mounted upon an adjustable bracket m Between these reeds are disposed the parting-bars m, said parting bars being mounted in a suitable bracket m, that is adjustabl y sustained upon the vertical and adjustable upright m carried by the support.

The warp-threads n extend first through the reed m, thence are parted and laid even by the parting-bars in", then extend through the reed m, then under the nearer of the pair of rollers i then over the beam "5, then under the other roller 2 and then upon the' s for this gong is receiving-beam. It will be seen that by pushing inwardly on the knob of either rod 70, so as to disengage its key from one of the notches 1 the corresponding roller 71 may be moved, so as to either tighten or release the tension upon the threads. An extreme and positive tension may be maintained by effecting an engagement between each key k and the upper one of the two notches j in each guide; but, if desired, the levers t carrying the rollers, need not be locked down, but the tension can be maintained simply by the weight of the rollers and the several parts movable with them. It will be seen that the two rollers i when in action tend to spread the warp threads over a considerable portion of the surface-jot the beami and thus they are prevented from slipping thereon.

pis-a circular box orcase having its front wall removed and provided on its rear face with projections p, from which extend threaded pins 19 that are adapted to penetrate one of the standards 11 and receive nuts for securing the casing in position to said standard.

In the rear wall p of this case is formed a recess p, in which vis disposed a spiral spring 19 that is coiled about a shaft 1). Near its outer end and within the, casing this shaft carries a collar p and also a disk 12 which takes the place of the front wall of the easing and which is kept from rotating relatively to said collar bymeans of a pin 1),

that projects from. the collar and penetrates said-disk? "The collarhas an integral wornn wheel p formed with it, whose ge eth engage the threads of asvorm q,'th'atishiounted upon a shaft q, journaled in arms g projecting from the rear wall of the case, said shaft q also carrying another worm-wheel q, that engages a worm q", mounted upon the end of the adjoining trunnion of the beam 2'. The trunnion of course projects into the casing, and in order to get the wo'rmand trunnion in place the circular wall of the case isprovided with an opening and the' rear wall with a communicating slot q. I The slot and the opening are eoverdby an angle-plate having a recess (1 in its lower end, whereby it fits over the shaft, being secured over the opening upon thetop of the casein any desired manner. j

sis a gong that is secured in the casing and slightly protrudes therefrom. The hammer that is secured inside of the casing and to the rear wall thereof, the pivot 8 from which the ar1n of the hammer projects, being provided with a tappet 3", that is adaptedto be engaged by one end of a double-pointed pawl .9 the free end of said pawl being so disposed as to be engagedby pins 3 projecting inwardly from the disk 1') and disposed at uniform intervals about the center of said disk.

is a knob that is loosely secured to the shaft outside of the disk 12 by means of a screw 15', penetrating it and extending into'the shaft, being prevented from rotation relaf ulcrumed in a bracket 5 Ca I tively to the disk by the pin 1), which projects into it. x

The outer face of the diskp may be marked off in graduations, which constitute a scale 2?, which may be read by means of a pointer i that projects from the angle-plate g It will be seen that as the beam i rot-ates its trunnion will impart, through the worm q, the worm (1 the shaft q, the worm q, and the worm-wheel 10 a rotary movement to the disk 19 As often as one of the pins sf is brought into engagement with the pawl s the v, hammer will be actuated and the'gong sounded. The amount of material that has been passed over the beam i'" can be determined at any time by reference to that markuipon the disk to which the pointer refers; ,If at any time it is desirable or necessary'to manually operate the indicator, so as to set it back, for instance, it is only necessary to press the knob against the action of the spring 10 until engagement between the worm-wheel 10 and worm q is broken, whereupon the disk maybe turned without reference to the means which automatically rotates it.

Referringagain to the mechanism whereby power is transmitted to the beam from the main drive-shaft, it is to be remarked that by virtue of thearrangement and construction of parts which we have described, with reference especially to the friction-disk, the beam can be thrown into operation very gradually, and so the undue and sudden strain that would otherwise be exerted on the threads and that is, in fact, exerted on them by warping-machines at present in use is obviated.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is
